4.1.2 The use code of the profiled board is as follows.

a) The roof panel use code is indicated by the initial letter "W" of the word "house" in Chinese Pinyin;

b) The wall panel usage code is represented by the initial letter "Q" of the "wall" Chinese pinyin.

4.1.3 The plate type feature code is represented by the combination of wave height (mm), pitch (mm) and coverage width (mm) of the profiled plate.

4.2 Profile type indication method

Example 1. A roofing profiled plate having a wave height h of 51 mm, a pitch d of 360 mm, and a cover width B of 720 mm, codenamed W51-360-720.

Example 2. A wall profiled sheet having a wave height h of 35 mm, a pitch d of 250 mm, and a cover width B of 750 mm, code-named Q35-250-750.

7.1.4 The chemical composition, mechanical properties, surface quality, dimensions and shape tolerance of stainless steel plates or strips shall be consistent with GB/T 34200, GB/T 3280 provisions. See Appendix A for the physical properties and mechanical properties of commonly used stainless steel sheets or strips.

See Appendix B for the surface finish types of stainless steel and steel strips. See Appendix C.

7.1.5 Stainless steel plates or strips shall be of the type and grade listed in Table 2. Recommended environment for various grades of stainless steel plates and strips See Appendix D.

The grades 022Cr12 and 10Cr17 should be coated with an organic coating.

7.1.6 The organic coatings adapted to the stainless steel substrate are shown in Table 3. The type of organic coating should be selected according to the processing and use conditions. Coating quality The ground is evenly distributed, and the coated plate is bent by 180° around a mandrel having a diameter of 3 t (t is a plate thickness), and the coating should not peel off.

7.2 Production method

The profiled sheet is formed by cold rolling stainless steel or steel strip substrate or coated sheet by roll bending or cold forming.

7.3.2 Surface quality

The surface quality of the profiled sheet shall comply with the requirements of Table 5.

1 After the profiled sheet is formed, the surface quality of the substrate is molded, and the substrate should not have cracks.

2 After the profiled sheet is formed, the surface quality of the coating is not affected by visible cracks, peeling and scratches.

3 Shape and surface quality after molding
